    Disc calipers need more fluid than rear drums so the larger reservoir goes to disc.

    Yes, if your brakes are the same size all around, you'll want an adjustable valve for the rears to prevent them from locking up before the fronts.

    Just finished my conversion, and WOW. cant say enough good about this. It stops now like a modern car! A+ rating for this DIY project.

    Some point of note for me:
    1. I had to buy a hub puller.
    2. I had to clearance some material from inside the caliper. The OD of the rotors touched the calipers slightly.
    3. I had to buy an expensive, odd sized drill bit to drill out my stud holes in the rotor
    4. I installed a new dual reservoir master cylinder. that means i had to fab up a new mount for it, and yes, a new push rod to go along with that. luckily i have some 4" angle scrap on hand.
    5. I purchased a proportioning valve for the back brakes that had the tail light hookup incorporated directly into it
    6. I bought metric bolts to 3/16" line, this way I eliminated one more conversion nut/possible brakeline failure point
    7. I replaced every last brake line with new hard line or flex line as needed

    Overall it went smooth. If I focused more, and had all the tools and parts on hand, I'd say an easy 4 day job of taking your time and doing it right. It's a night and day difference onvce complete.

    now, do i do this to my '70cj with the dana 27, or do i regear the dana 30 that has disks on it already?

    Dana 30 so we know how they compare side by side.

    Very cool. I swapped a drum 25 to NT30 with disks and that was night and day. I do like my NT30 swap. It's one of the mods I'd definitely do again. Even if you keep the Ross, you'll get crossover steering.

    I have a disk NT30 if you need one and am planning on going to Aniwa this year.
